Q: Despite the fact that we regularly have sex at least twice per week, my husband claims that we rarely, if ever, have sex. Is this because it's completely unmemorable for him, or is something else happening? (Obviously, I feel like it's the first thing.)

A: No, no, it's not bad sex. Don't take it so personally. Some guys have no sexual memory whatsoever: We can have the craziest, most mind-blowing sex ever, and half an hour after it's over, I'm wondering why we haven't had sex in a while. Seriously, when you're a "pent up" guy waiting for an opportunity for sex, you're basically existing in dog years. Every hour feels like half a waking day; every day without sex feels like a week; and every week is like a long frustrating month-and-a-half. Think of it as the "Male Dog Sex Ratio."
